But if you're into tech and haven't been to Singapore, I'd recommend going... But know that it might make you apprehensive.
The backend structure to support that number of cameras alone, has to be ridiculous. Every subway station is surrounded by 20 cameras, there are 3-5 looking at you as you enter, there are 20 more before you get to the platform where there are 10 that can see you. There are poles on the street every 2-4 blocks that have 8-10 cameras around them. The further you get away from downtown the more "relaxed" it is I'm sure but it was a pretty crazy place.
I had just figured with the amazing infrastructure they have that they also would have world class security. But what do I know!?
